MFC CFormView OnKeyDown event not triggered

I have a CFormView and I have some controls on it. I have implemented an OnKeyDown event on my CFormView. Everything is good, except my event is never triggered because the focus is on a combo box in my CFormView. I don't want the combo box to receive the event. I want the CFormView to receive it. So I implemented PreTranslateMessage(MSG* pMsg) and it removes the event from the combo box but it never gives it to the CFormView. Here is the code:

BOOL CfinalprojView::PreTranslateMessage(MSG* pMsg) { 
if( pMsg->message == WM_KEYDOWN ) {
    SendMessage( WM_COMMAND, MAKEWPARAM( IDD_FINALPROJ_FORM, BN_CLICKED ), ( LPARAM )0 );
    return TRUE; 
} else if( pMsg->message == WM_KEYUP ) {
    return TRUE; 
} else {
    return CFormView::PreTranslateMessage( pMsg );
}}

What am I doing wrong?

Thank you in advance,

Corneliu

So, it seems that there is no way to forward the key events to the CFormView. Instead, one can catch the events in PreTranslateMessage(MSG* pMsg) and check the key that was pressed like this:

BOOL CfinalprojView::PreTranslateMessage(MSG* pMsg) {
    if( pMsg->message == WM_KEYDOWN ) {
        if( pMsg->wParam == VK_DELETE ) {
            ...
        }
        return TRUE; 
    }
    else if( pMsg->message == WM_KEYUP )
        return TRUE; 
    else
        return CFormView::PreTranslateMessage( pMsg );
}
